Add off-thread support for class boilerplate allocation, removing a previously "unreachable" overload. Notably, this requires support for off-thread allocation of Dictionaries and DescriptorArrays. Due to template fun, the off-thread allocation of Dictionaries in particular requires some amount of boilerplate (no pun intended).

When an empty class is nested inside a class with private instance methods, like this: class Outer { constructor() {} #method() {} factory() { class Inner { constructor() { } } return Inner; } run(obj) { obj.#method(); } } The bytecode generator previously generate private brand initialization for the constructor of Inner by mistake, because during scope chain serialization/deserialization, the outer scopes of Inner and factory() are not allocated or serialized (as they are empty). In the eyes of the bytecode generator, it then appeared as if Outer is the direct outer scope of Inner's constructor. In order to work around this information loss, in this patch we rely on SharedFunctionInfo instead of the Context/ScopeInfo chain to maintain the information about private brand initialization. This is done by shrinking expected_nof_properties to 8 bits and freeing 8 bits for a second bitfield on the SFI.

Remove Isolate parameters from some dictionary methods, and change others to use ReadOnlyRoots instead, to prepare for Isolate templatization in a future patch. One small side-effect is that the global dictionary's property cell's dependent code deoptimization has to dynamically get the Isolate when it needs to actually mark code for deoptimization, for method signature consistency. Given that this is the slow path anyway, it shouldn't matter.

Add the remaining missing templatizations to allow an initial wiring in of the off-thread factory into streaming compilation finalization. The off-thread finalization is behind a flag, disabled by default: --finalize-streaming-on-background When the flag is enabled, background tasks will perform perform the finalization during their background execution, and will release the parser and compilation jobs once they are no longer needed. The implementation is complete enough for performance testing, but not enough for launch. Notably, there is no support for: * Class boilerplates (the code is marked unreachable), * Exceptions during finalization, i.e. parse/compile warnings/errors, * Allocation sampling, * Logging, * Asm.js, * Parallel complication tasks * Forced source positions (for "NeedsDetailedOptimizedCodeLineInfo()") This patch also adds some tracing events for the various stages of the off-thread finalization (including the main-thread merge) for further performance improvements.

Although AccessorInfos are technically mutable, in practice they are not mutated after initialization, and they are guaranteed to be immortal and immovable. So, we can safely make them accessible from the off-thread factory, as long as the user promises to not try to mutate them. This is necessary for off-thread class boilerplate creation.

Also improve type collection by parsing TORQUE_INSTANCE_CHECKERS_SINGLE_FULLY_DEFINED, as we were missing several types with the previous heuristic (like StackTraceFrame, PromiseReaction, and many others). This will include 96 new v8dbg constants which can be used by debuggers like llnode.
